Abstract
Assuming that there are perpetual roads solution of the problem pertaining to strength and longevity of road concrete pavements are mainly determined by theoretical prerequisites which are considered as basic ones in technology for strengthening micro-structure of their top surface layer. Application of fine grain concrete with ultra-disperse additives partially helps to obtained strengthened top layer of such pavements. At the same time further search and improvement of theoretical analysis for the given problem are required for development of technological parameters. Investigations on this direction are rather insignificant and the problem continues to be considered as an actual one. There is a known method for application of colloid cement glue and activated gunite solution for strengthening binding of new and old concrete in engineering structures. However it is necessary to point out the fact that investigations in the field of protection of road concrete pavements against corrosion destructions are actually absent. Such approach restrains a wide application of the mentioned methods in engineering practice for provision of efficient maintenance of concrete pavements. In this case it is necessary to consider the existing theoretical statements on the essence of quantum structure-formation mechanics in the systems consisting of colloid-disperse particles. This approach to road concrete science is accepted a new one ant it is connected with the possibility to regulate processes of structure-formation micro-mechanics in mineral systems while creating protective surface layers in road concrete pavements. The given paper is devoted to this problem.
